AODD (Air Operated Double Diaphragm Pumps)
PP | PVDF | ALU | SS316L
Debem’s air operated double diaphragm pumps are ideal for pumping liquids with high apparent viscosity, even if containing suspended solids. The stall-prevention circuit guarantees a safe operation, without requiring lubricated air. These pumps have achieved unprecedented levels of versatility due to their self-priming capacity with a considerable suction head, the ability to fine-tune the speed without losses of pressure as well as the possibility of dry-running without suffering damage. The vast range of construction materials allows us to select the best chemical compatibility with the fluid and/or the environment, without neglecting the operating temperature range. The construction principle of the air operated double diaphragm pumps makes them ideally suited for demanding applications or potentially explosive atmospheres (ATEX – IECEx certification).

Remote Control
All the pumps of the RC line are ATEX – IECEx certified, constructed in polypropylene or PVDF in the plastic version or in aluminium or AISI 316 L for the metal versions. They are ideal for pumping liquids with high viscosity, even if containing suspended solids.
The vast range of materials available for the parts in contact with the fluid, such as pump casings and manifolds, diaphragms, balls, ball seats and o-rings, makes them compatible with any type of fluid present on the market. They can be used in numerous applications.
Sanitary and Food Pumps
Debem’s production range includes two lines of products designed specifically for the pharmaceutical and food sector:
-
SANIBOXER | 3A certified pumps, made with mechanically polished AISI 316 L
-
